Effect of Honey, Coenzyme Q10, and β-Carotene/α-Tocopherol as Novel Additives in Rabbit-Sperm Cryopreservation Extender

Animals, 2023
The effectiveness of rabbit-sperm cryopreservation is still below average compared to other domestic species. After the sperm cryopreservation process, post-thawing parameters like motility and membrane integrity are significantly compromised. The use of

The Effect of Semen Cryopreservation Process on Metabolomic Profiles of Turkey Sperm as Assessed by NMR Analysis

Biology, 2022
Semen cryopreservation represents the main tool for preservation of biodiversity; however, in avian species, the freezing–thawing process results in a sharp reduction in sperm quality and consequently fertility.

One‐Step Induction of Oogonia‐Like and Pro‐Spermatogonia‐Like Cells From Porcine Pluripotent Stem Cells

Advanced Science, EarlyView.
This study established a one‐step method inducing pro‐spermatogonia‐like (activating SOX17) and oogonia‐like (activating SOX17/TFAP2C) cells from porcine pgEpiSCs with a NANOS3‐tdTomato reporter. EGF activates the core PGC program and supports survival; BMP4 further induces NANOS3 and DDX4 expression; IWR1 enhances PGCLC efficiency by suppressing ...

Long-Term Experience of Sperm Cryopreservation in Cancer Patients in a Single Fertility Center

The World Journal of Men's Health, 2019
Purpose: Sperm cryopreservation before cancer treatment is the most effective method to preserve the fertility of male pa-tients. We present our 21 years experience with sperm cryopreservation for cancer patients, including an examination of se-men ...

Embodied attachments: IVF, the maternal body, and the making of embryo kinship

Feminist Anthropology, EarlyView.
Abstract Within the sphere of IVF (in vitro fertilization), there is increasing concern about the stockpiles of frozen embryos held in clinics across the country. This normative discourse tends to take the patient‐embryo relationship for granted, with salient political consequences for current embryo ‘personhood’ debates.

Advances in Cryopreservation of Bull Sperm [PDF]

, 2019
Cryopreservation of semen and artificial insemination have an important, positive impact on cattle production, and product quality. Through the use of cryopreserved semen and artificial insemination, sperm from the best breeding bulls can be used to ...

Monitoring Changes in Sperm Concentration and Quality Help Improve Captive Breeding Outcomes of the Endangered Amphibian Rawlinsonia littlejohni

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Amphibians are among the most threatened taxonomic groups, with many species experiencing rapid declines that have resulted in small, isolated populations vulnerable to inbreeding depression and reduced fertility. One major outcome of inbreeding is lowered fecundity, often linked to morphological changes in gametes.
